The following is an excerpt from the m file in that project: The OLEDragAndDrop sample application contains the code necessary to implement the drag-and-drop operation in Visual Basic 6. Note that this cycle applies to both control-to-control and application-to-application drag and drop. Figure 10-5 outlines the life cycle of a drag-and-drop procedure in Visual Basic. This change simplifies the programming burden for new development but requires the rewriting of drag-and-drop code for existing applications. Drag and drop between controls is handled in exactly the same manner as drag and drop between applications. NET, the drag-and-drop operations have been consolidated into a single framework. Life cycle of a Visual Basic 6 drag-and-drop operation. The next section moves on to how things are done in Visual Basic. Figure 10-3 shows an image from the sample OLEDragAndDrop application.įigure 10-4 outlines the life cycle of an OLE drag-and-drop operation in Visual Basic 6. This sample should give you a better idea of exactly what changes you will need to make in your own application. It permits the user to drag and drop image files to and from the application and implements OLE drag and drop in full manual mode. To better illustrate how the upgrade process affects OLE drag-and-drop operations, we have provided a sample application named OLEDragAndDrop on the companion CD.

Table 10-2 Visual Basic 6 Controls Grouped According to Their Support for OLE Drag and Drop

Table 10-2 lists the standard Visual Basic 6 controls and their support for manual and automatic drag-and-drop operations. The standard Visual Basic 6 controls have varying degrees of support for OLE drag-and-drop operations. OLE drag and drop was designed to support drag-and-drop capability between applications and is the focus of this section. Standard drag and drop is intended to support drag and drop between controls within a single form. Visual Basic 6 supported two kinds of drag-and-drop operations. To better understand how these changes will affect your application, let s take a quick overview of this feature. There are a number of important differences between Visual Basic 6 and Visual Basic.

Drag-and-drop capability is an important function of most modern applications.
